AbolishedZirconium and zirconium alloys--Determination of hafnium content--Emission spectrographic method
锆及锆合金化学分析方法 发射光谱法测定铪量
Application Summary AI generated
This standard specifies an emission spectrographic method for determining the hafnium content in zirconium and zirconium alloys. It is applied in the metallurgical industry for quality control and material certification, particularly in the production and testing of nuclear-grade zirconium where hafnium must be precisely measured due to its high neutron absorption cross-section.
